Space between number and unit in visu

[Thomas]

Hi
I'd like to add a space between number and unit in visualisation.
Unfortunately it looks like units are not wrapped around in div.

<div class="item item-control item-value item-backdrop" style="top: 531px; left: 135px; z-index: 71; font-size: 12px; color: rgb(255, 255, 255);">50%</div>

Do you have any idea how to do it?
I mean javascript etc. Not adding an extra space to units definitions because it's ugly.

Just fill in a unit in the object with a leading space instead of using the auto created unit

I don't want presentation style in data. Because typos can differ betweeen countries etc. Plus I wrote "space" but what I exactly want is non-breakable space or better non-breakable short space.
Isn't there any other way? Like inject visu web page bootloader and change the generated DOM?

You can put any UTF-8 characters into the units field, including non-breaking space.
